Feature Request: I would like a option that after deleting a mail it will deselected and don't jump to a new mail. I want the same functionality, as if I open a mail with double click and delete it, for preview (is it called so?). There is already existing an add-on named "Deselect on delete" (https://addons.thunderbird.net/en-US/thunderbird/addon/deselect-on-delete/) which does it perfectly, but I miss a default option from Thunderbird itself. I don't know if the developer will update this addon to work with Thunderbird 69, so I hope, you can integrate this functionality in Thunderbird. Thank you very much.
